Energy Meters and Power Meters for Australian Industry
You can't manage what you don't measure. An energy meter shows exactly where power is used across a site, from the main incomer down to a single machine, pump or tenancy. That data helps you cut energy costs, find faults early, recharge tenants accurately and report on energy use with confidence.
DAANET is the authorised Australian distributor for Carlo Gavazzi. We supply a full range of Carlo Gavazzi energy meters and power analysers locally, from compact single phase DIN rail meters to 3 phase power analysers, multi circuit meters and DC meters, and we help you choose the right meter for each point on your site.
Why sites install energy meters
- Sub metering: measure energy by building, floor, production line or tenant, not just at the main meter.
- Cost control: see which loads drive peak demand and where energy is being wasted.
- Maintenance: spot changes in current, power factor or power quality before they become breakdowns.
- Reporting: collect reliable data for energy audits, sustainability reporting and management reviews.
- Automation: send live energy data to a PLC, SCADA, BMS or cloud platform over Modbus, M-Bus or Ethernet, depending on model.
Which energy meter do you need?
Start with three questions: is the circuit single phase or 3 phase, can the meter carry the current directly or does it need current transformers, and how will the data be read?
| Meter type | Best for | Carlo Gavazzi ranges we supply | Shop |
|---|---|---|---|
| Single phase DIN rail energy meter | Sub metering single phase circuits, small tenancies, individual loads | EM111, EM112, EM511 (direct connection up to 45 A on some models, or via 5 A CT) | DIN rail meters |
| 3 phase DIN rail energy meter | Switchboards, motors, pumps, production lines | EM24, EM330, EM340, EM530, EM540, EM580 (direct connection up to 65 A on some models, or via CT) | DIN rail meters |
| Panel mount power meter and analyser | Main switchboards and MCCs where you want a front panel display and power quality data | WM20, WM30, WM40 modular power analysers, EM210 | Panel mount meters |
| Multi circuit energy meter | Measuring many circuits in one board with less wiring | EM270, EM271, EM280 with split core current sensors | Multi load metering |
| DC energy meter | Solar PV, batteries and EV charging | DCM1 DC meters, DCT1 DC transducers (up to 1000 V and 300 A on listed models) | DC metering |
| IoT energy meter | Sites that want energy data in the cloud without a separate gateway | EMS10 and other all in one IoT meters | IoT meters |
| Current transformers | Measuring larger currents with CT connected meters | Solid core, split core and Rogowski coil CTs | Current transformers |
Communication options
Depending on the model, Carlo Gavazzi meters offer pulse outputs, RS485 Modbus RTU, M-Bus or Ethernet, so energy data can go straight into your PLC, SCADA, BMS or energy monitoring software. Some models carry MID certification for billing applications; check the model's data sheet or ask us.

Frequently asked questions
What is the difference between an energy meter and a power meter?
An energy meter records energy used over time, in kWh. A power meter, or power analyser, also shows live values such as voltage, current, kW, power factor and often harmonics. Many Carlo Gavazzi meters do both.
Do I need a 3 phase energy meter?
If the circuit you are measuring is 3 phase, such as a motor, pump or switchboard feed, yes. Single phase meters suit single phase circuits and smaller loads.
What is a DIN rail energy meter?
A meter that clips onto the standard 35 mm DIN rail inside a switchboard, so it can sit beside breakers without cutting the panel door.
When do I need current transformers?
When the current is higher than the meter's direct connection rating. The meter then reads the current through CTs fitted around the cables.
Can the meter connect to my PLC or BMS?
Most models have Modbus RTU, M-Bus or Ethernet options. Tell us your system and we will suggest the right version.
